When we enroll two UKIs with different PCR pub keys into one LUKS slot/ token each, then we can encounter the wrong one and should not give up but continue iterating instead of requiring the passphrase. Similarly, a pcrlock token might be for another UKI and we should continue the search. Same for a token that is meant for another TPM (e.g., external storage). While this is mainly about cryptsetup's automatic unlocking from the initrd, it also matters for usage in the system, e.g., for other storage and when cryptenroll should unlock using the TPM. There are two code paths, one is the libcryptsetup plugin and the other is the fallback when that's not available. To let the libcryptsetup loop continue to iterate, remap the above error conditions to EPERM. For the fallback path check all of them (no remapping) and continue iteration. For better log output, include the token ID to be able understand which token fails.
